412 ??
11/29/23 at 03:48:08

I have my 05 running good enough to start taking some day trips. The last item I need to address is the rear suspension. I have VS800 shocks on it and it is a significant upgrade from the oem. I am interested in Progressive 412 shocks; although, I am not sure if the standard or heavy duty would work better. I suspect the correct spring weight would be somewhere in the middle for me. I am leaning towards the heavy duty as a I wight 215. With gear and tail bag suspect I am getting a bit to heavy for the standard.

Can someone who has experience with them offer some insight? Thanks

Best regards,

I am not sure you want Heavy Duty springs.......the 412 shocks are likely made for larger/heavier bikes than the Savage.

I have 412 shocks on my Cafe', and the standard springs (120/170) were too stiff. I ended up ordering lighter (105/150) springs and the ride is much better. I do believe the valving could be a bit too heavy for the Savage....the small pavement ripples are pretty noticeable, bigger bumps are handled pretty well.

My bike weighs 320, I weigh 170.....probably more like 185 with my gear on and ready to ride (My boots are heavy Wink

).

I bought the 412-4005 (11") and had to use the highest preload setting at 230# and still were a little light.

I think the vs800 intruder shocks are much better. They are longer at 11 1/2" and might have a little more travel.

I have the VS800 shocks on them and I think the valving on them is kaput. It is like a yo yo going over bumps. I bet I would be pretty happy with decent ones. I though the 412s may be a good option. I'll have to do some more research. Best regards,

Ya, I think the damping is a little low but you don't go bouncing down the road so it takes the harshness out of rough roads.
